LIGHT-DIMMER.

Application filed September 6, 1916. Serial No. 118,747.

To all whom it may concern:

Be it known that I, ALBERT A. a citizen of the United States, residlnAszMAN, at

. Rahway, in the county of Union and tate of New Jersey, have inventednew and useful Improvements in Light-'Dimmers, of

.which the following is a specification.

This invention relates to headlight dimmers, and has for its principalobject the provision of a device of this character which may beexpeditiously applied to any well known' form of head light such as thatused posedin the line of projection of the light rays passing from theburner so as to soften the brilliancy of said light rays and therebypermit the head light to be used upon public highways without theobjectionable dazzling eifect of the light upon the eyes of edestrians.

, other object of the invention resides in the provision of a device ofthis character which will consist of a foraminous body having a portionbelow its horizontal center provided with a relatively large opening,

the perforations in the body being closely related so as to cause aneffective softening of the light rays and yet diffuse the same andeflectually cause the light rays to be scattered in a downward directiontoward the mentioned opening where the surface of the highwayimmediately in advance of the vehicle will be properly illuminated.

With the above and other objects in view which will appearas the natureof the invention is better .understood, the same consists in theimproved construction and novel arrangement of parts which will behereinafter more fully described and particularly pointed out in theclaim.

Inthe accompanying drawing, has been illustrated a preferred form of theinvenvtion, it being however understood, that no limitation isnecessarily made to the precise structural details therein, exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to i when desired.

In the drawings 4 Figure 1, is a vertical sectionthrough a Specificationof Letters Patent.

portion of a headlight showing the appli-' cation ofthe inventionthereto.

Patented Aug. 14, 1917.

Fig. 2, is a'rear elevation of the device removed from the head-light.

Fig. 3, is a similar view showing a slightly modified form of theinvention.

Fig. 4:, is a horizontal the line 44 of Fig. 3.

The dimmer consists of a. foraminous body 1, which in thepresentinstanceis consection taken on structed of sheet metal having thesame uniform thickness throughout. The openings 2, which are formedin'the body are closely related to one another, providing interveningopaque portions of the body between the perforations. In thisimanner thematerial is rendered translucent and the light rays will be immediatelyobstructed on their passage from the burner of the 'head light.

The head light shown herein is a well known design and the dimmer isconstructed so as to operatively accommodate itself directly at the rearof the lens carried by the usual swinging closure. In order that thelens may be securedin position in the opening of the head light closurelugs A are provided. The foraminous body 1, constituting the dimer is ofa size whereby it will nicely accommodate itself to. the lens andcompletely extend over the same, being substantially translucentand thelight rays will be difi'used and the sharp brillian'cy will beconsiderably moderated so as to eliminate the dazzling glare of lightupon the eyes. The marginal edges of the disk like body 1, are providedwith notches 3, which are adapted to receive the lugs A upon the closureof the head light. Provision is thereby made for properly accommodatingthe device to the lens or for uniformly associat ing the same therewith.Below the horizontal center, the body 1,

s provided with a relatively large opening 4, so that the'light as it isdiffused by the purpose. The device is strong and'durable, compact andsimple of construction and when not in use may be conveniently car riedupon the vehicle without occupying much space. V v

' In the modified form of the invention shown in Figs. 3 and 4 the body1 is provided with a main perforated portion 2 having an additionalelement'of foraminous material indicated at 3 and disposed at I one sideof the main body. The said member 3 is preferably corrugated verticallyand it is found that in so doing and by fication is identicalconstruction with the form described in the preferred embodiment.

What is claimed as new is A light dimmer comprising a disk pro- I videdwith. a number of relatively small openings, said disk also having arelatively large opening, and a corrugated perforated sheet of materialattached to the side of with the small openings.

In testimony whereof I aflixemy signature in presence of two witnesses.
